Hot direct reduced iron (HDRI) is DRI that is transported hot, directly from the reduction furnace, into an electric arc furnace, thereby saving energy. The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles.

Iron-rich rocks are common worldwide, but ore-grade commercial mining operations are dominated by the countries listed in the table aside. The major constraint to economics for iron ore deposits is not necessarily the grade or size of the deposits, because it is not particularly hard to geologically prove enough tonnage of the rocks exist.
Iron ore is found in nature in the form of rocks, mixed with other elements. By means of various industrial processes incorporating cutting-edge technology, iron ore is processed and then sold to steel companies. The iron ore produced by Vale can be found in houses, cars and household appliances.
Limonite, or brown ore, is to be found at the bottom of some bogs and shallow lakes, in favorable situations, where the weathering rocks have yielded iron to the water draining into these basins. The limonite accumulates so fast in some places that a lake bottom may be cropped again after a number of years, as at Radnor Forges, Quebec.

Sep 20, 2019 In the case of steel, this requires that the iron be liquid, and the other atoms allowed to mix with it. We normally do this by smelting iron ore (primarily Fe2O3) with coke in a blast furnace. This produces liquid iron with a carbon content of about 4% (the saturation level of carbon in iron).

In this machine the raw ore, after calcination was fed onto a moving belt which passed underneath two pairs of electromagnets under which further belts ran at right angles to the feed belt. The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present.
The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being
